Research on a signal processing method for bionic polarization compass

太阳光在大气层传输的过程中,由于大气散射作用就形成了包含重要导航信息的大气偏振模式,很多昆虫能够利用大气偏振模式来获取罗盘方向。根据昆虫检测天空偏振光和译码偏振信息的生物机理,研究了一种模拟昆虫偏振敏感神经元的网络模型。该网络模型采用简单的数学运算,对仿生偏振罗盘检测的偏振信息进行处理。仿真结果表明:该信号处理方法能够准确地获取罗盘方向。

Atmospheric polarization pattern includes significant information, which is caused by the sunlight seatterning during the process of transmission. Many insects gain directional information using the atmospheric polarization pattern. According to the insect biological mechanism of detecting polarized light and decoding polarization information, a network model which imitated insects polarization-sensitive neurons is researched. The network is used to process the signal of bionic polarization compass by simple math computation. Simulation result shows that this signal processing method can accurately obtain compass direction.
